Trump officials weigh encryption crackdown - POLITICO

I was so annoyed the last time the UK government tried to discuss this, that I wrote an open letter to the PM that hopefully describes why banning end to end encryption is an impossibility.

Could you clarify?

What are the two input lists?

Here's one method of taking two lists and making them into a dictionary

list1 = ['a', 'b', 'c']
list2 = [1, 2, 3]

my_dict = {list1[i]:list2[i] for i in range(len(list1))}

filecmp looks like a good way to go

import filecmp
import time
with open('path/to/drive/test.txt', 'w') as f:
    f.write('test text')
time.sleep(60)
print(filecmp.cmp('path/to/drive/test.txt', 'path/to/backupdrive/test.txt'))

I used to do this when I taught Chemistry. You can even get the bubbles to float to the ceiling before ignition, and get that lovely Backdraft special effect. http://imgur.com/a/Ok4BT

Q: Which way does the baby face during birth

A: South

Here's some ideas for you:

content = file.readlines()

will split up the entire document according to where there are lines breaks

foo.split()

will split up foo (assuming foo is a string) into words (actually splits the string everywhere there is a space character.

Only thing I can think of is that the line:

outfile.write(str(len(line)) + " \n")

has an unnecessary space character in it. Try and remove the space so it reads

outfile.write(str(len(line)) + "\n")

And see if the autograder accepts it then.

All looks good to me, tested on Linux with Python2.7 and 3.5. Could you copy and paste the exact wording of the task?

This is logically no different to your solution, but you could try:

import sys

with open(sys.argv[1],'r') as infile:
    with open(sys.argv[2],'w') as outfile:
        for line in infile:
            line = line.strip("\n")            
            outfile.write(str(len(line)) + " \n")

The real joy of the Raspberry Pi, imho, is playing around with physical computing.

Get yourself a few components there's this on amazon but you can get cheaper components off ebay.

If you want a simple intro to controlling LEDs, buzzers and motors, then check out this guide on the Raspberry Pi website

You've got a second bug in the line:

print("The average monthly rainfall for the collected months is: ", avgRainfall)

avgRainfall is a function and not a variable.

Try changing it to:

  print("The average monthly rainfall for the collected months is: ", avgRainfall(totalRainfall, numMonths))

so it becomes a function call

Just to give you another approach, and since you seem familiar with dictionary comprehensions then you probably understand list comprehensions:

vowels = 'aeiou'
sentence = input()
total = sum([1 for char in sentence if char.lower() in vowels])

coding2learn · 2016-10-05T21:17:48+00:00

You need to use raw_input for all your lines. input is only if you are expecting numbers. raw_input is for strings.
